The GOP candidate’s critique is described in the video above. Hinckley also staged a sidewalk news conference near Whitehouse’s Providence office this afternoon to amplify his message.

Whitehouse’s campaign manager, Tony Simon, didn’t respond to requests for comment. declined to respond directly to Hinckley’s accusation of hypocrisy. Simon called Whitehouse a leader in pushing for greater transparency on political contributions.

As a challenger facing an incumbent with a staggering financial advantage, Hinckley is trying to turn his opponent’s fundraising prowess into a liability. By contrast, Hinckley estimates he’s received roughly $10,000 to $20,000 in PAC contributions.

State Treasurer Gina Raimondo’s impressive fundraising prowess will be among her assets if — as many expect – she runs for governor in 2014. Providence Mayor Angel Taveras, another prospective contender for the post,lagged behind Raimondo ($258,155) in Q2 even though he had solid numbers ($114,810).

But money isn’t everything in some contests, and there’s no guarantee the candidate with the biggest war chest will win the next gubernatorial election.
